Specification of Letters Patent.

' Patented Nov. 5, 1907 Application filed September 29.1906. Serial No.336,764-

To all whom it may concern:

Be it known that I, GEORGE J MILLER,.8. citizen of the United States ofAmerica, residing at Kansas City, in the county of Jackson and State ofMissouri,- have invented certain new and useful Improvements in BroilingApparatus; and I do hereby declare that the following is a full, clear,and exact description of the invention, such as will enable others tomake and use the same, reference being-had to the accompanying drawings,forming apart of this-specification.

. The object of the invention primarily is an apparatus for broilingmeats, poultry, etc., in which the meats to be broiled may be turnedquickly when exposed to the fire and the juices thereby preserved.SecondThe turning of-the broiler while being elevated in position abovethe heating grate. Third-To communicate a down draftto the smoke andvapor during theprocess of broiling. Fourth'-To enable the attachment ofany draft apparatus for forced draft.

The invention consists in the novel construction and combination ofparts such as will be first fully described and'then specificallypointed out in the claims.

In the drawingsFigure 1 is a view in perspective of the novel broilingapparatus, aportion .of the case or frame being-b oken away to show thesupport-for the inner ends of tne removable ventilating and heatinggrate. Fig. 2 is a plan view of the apparatus with the broiler removed,the heating grate being broken away to show the lower chamber and theaperture and cover in the bottom of the chamber. Fig. 3 isa transversevertical sectional view of the apparatus as seen in Fig. 1. Fig. 4 is anend view ofthe upper portion of the frame showing the broiler supportingframe and the broiler rotating devices in an upwardly extended position.Fig. 5 is a detail side View enlarged of one of the outer jointed barsconnected with the broilershowing the ratchet teeth in the jaw or yoke.Fig. 6 is a plan view of the jaw or yoke showing the-ratchet teeth. Fig.7 is a detail side-view of the separable supporting plates for thetrunnions of the broiler on the broiler supporting frame. Fig. 8 isatransverse' sectional view enlarged of the trunnion showing the ratchetteeth thereon. Fig. 9 is a detail view of the adjusting bolt and nut forthe jointed arms. Fig. 10 and 10 are views of the outer jointed barconnected with the broiler as seen in Fig. 5 and 6 without the ratchetteeth. Fig. 11 is a modified view in perspective of the broiler raisingand lowering and turning devices, the lower portion of the case or framebeing broken away. Fig. 12 is a view of a modification of the broiler.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawing.

Referring to the drawings 20 indicatesa rectangular shaped case or framecomposed of the sides 21, 21 22,

22 and bottom 23, preferably constructed of thin metal. In the end 22,22 of the case at points equidistant from the sides 21, 21 extending ashort distance downwardly from the upper horizontal surfaces of saidends are oblong openings or slots 24, the

lower surfaces of which openings are curved in the arc of a circle.-

Upon the inner surfaces and ends of the case or frame are secured thehorizontal broiler supporting flanges 25 which extend from the innersurfaces of one side of the box to the inner surfaces of the othersideand a slight distance below the line of the lower curved surfaces of theopenings or slots 24.

Upon the inner surfaces of the ends 21, 21 at points equi distant fromthe upper and lower horizontal surfaces ofjthe box-are horizontalflanges 26 of the same length as the flanges 25, the flanges upon oneend 21 of the box being short in length as further described.

The flanges 26 support-a ventilating and fuel burning,

grate 27 extendingtransversely to the box and beneath which grate is achamber 28 for smoke and vapor arising from the broiling of the meats orother food. In the side 21 of the box is an opening or flue 29 leadingfrom the chamber 28 and upon thev outer surface of. said side extendingaround said opening is an annular flange or collar 30 and inwhich'collar as shown is fitted a flanged cover 31. The fuel burning andventilating grate 27 consists ofpipes or burners 32 perforated at 52upon their upper surfaces, said pipes extending from the.

inner surface of one end 22 nearly to the inner surface of the other end22 and closed by suitable plugs 33 at each end. -A series of pipes orburners 32 are employed extending parallel with eaclnother. In theend'22 of the box opposite the ends of the pipes or burner 32am openings35 through which extend the nipples 36 which are smaller incircumference than the pipes 32, the inner ends of which nipples extendthrough the plugs 33 a short distance within the pipes 32 and supportsaid pipes detachably in position. Extending in the longitudinaldirection of the pipes 32 and laterally from the opposite surfaces andin the line of the diameterof said pipes are short flanges 37 and fromthe outer surfaces of the flanges extend the plates or 'webs 38-, whichplates are curved'in the arc of 'acircle and the upper'en'ds of whichplates extend a short .distance above the line of the horizontal uppersurfaces of thesaid pipes'and to a position a short distance from avertical line extending through grate equi distant from said pipes thusforming between the outerlongitudinal surfaces of adjacent parallelplates 38 the-longitudinal slots or ventilating openings39; Upon -theends of the plates 38 of the box are lugs 40 which rest upon the flanges26.

The portions of the grate'adjaoent to the inner surface of the side 21of the box'consist of narrow plates 41, supported upon the flanges 26,at one end and the end 21 of the box and also upon the short flanges 26upon the end 22 of the box. In width these plates 41 extend from theinner surfaces of the sides of the box to within a short distance of thelongitudinal outer surfaces of the plates 38 thus leaving a slot oropening of the same width as the slot or opening 39 between the suriacesof adjacent plates. Upon the outer ends of the nipples 36 are internallyscrew threaded caps 45, in which are ordinary cut off valves and withwhich valves are connected the valve stems 47 which extend through thesaid caps 45 and upon the outer ends'cf said stems are wheels or handles48. With the lower surfaces of the sides of thecaps 45 are connected theupper endsoi short pipes 49 and with the lower end of one of saidzpipesis connected anelbow 50 and with thegother pipes the three way pipeconnections 51 the elbow and one of said connections being connected bymeans of a shortlength of. pipes 52, the other connections 51- beingconnected by a short length of pipe 53. 54 indicates a gas supply pipefor gaseous fuel and is connected with the source of supplyat one endand with one of the three way connections 51 at the other end;

In the bottom 23 of the box is avlargecircular opening 42' in the sidesof'which opening is fitted the annularflange 43 upon'the inner surfaceof the cover 44, which cover is larger than said opening and closes uponthe outer surface of the bottom 23 of said box.

55 indicates the broiler-which consists of two frames between which'themeat is placed for the purpose of broilingor roasting, the details ofconstruction of which broiler will be made the subject matter of aseparate application. For thepurpose of illustration it will be observedthe separate frames er the broiler com- I prise series of cross wires 55upon which the articles are laid and that the frames'are mounted on thetrunnions 56, the outer portions of the frames extending to within ashort distance'jof the inner surfaces of the sides.2l of the boxthelower flame resting upon the flanges 25 within the case and the outerends of the trunnionsextend. through the slots 24 in the ends 22, 22 ofthe case. Uponsaid outer end portions of the trunnions arewheels-.orhandles 57, The frames may be kept closed by awire'andhook54.i 58 indicates the device or lever for raising and lowering thebroiler which consists of-the rocking bar 59 and 60 arranged in positionnear the upper portions'of the sides 21" and 21 of the case and'a shortdistance from the outer surfaces of the case. The ends of these'barsextend a slight distance beyond the line ofthe ends 22, 22 of the case.The bar 59 is connectedrwith the outer leaves of inverted hinges 61arranged near the upper surface of the case, the inner leaves beingsecured rigidly to the case. With the outer ends of thebars 59 and 60are connected rigidly the lever arm-62 which extends parallel with theouter surface of the ends 22, 22 of the case and are bent 1 in adownwardly curved line from the bars 59 and 60 and below the line of thebottom of the slots 24 in the ends 22, 22 of the case and also bent atboth ends a slight degree inwardly. Connected rigidly withtheuppersurfaces ofv the curved lever arms 62 opposite the slots 2 4 areupwardly'extended plates 63 in which are'annularopenings or bearings 65for the trunnions 56, supporting the broiler 55 in the upper portions ofwhich plates are slots or openings 66, leading to the hearings oropenings 65 which slots permit the passage ofthe trunnions. The trunnionsupports or plates 63 as'shown are made intwo parts and riveted to theouter surfaces of the lever arms.

Upon the portion of the trunnions 56 extending beyond the flange 67 areratchet teeth 68% seenlin'cross 'sectionin liig. 8 ,fthese teeth beingmade to extend in the opposite direction to the direction oi rotation ofthe trunnions 56. Upon the ends 22, 22 iof. the"box and extending at anangle to and located ashort distance irorn the sides ot-the slots 24toward the'side 2'1 of'the case are the longitudinally grooved platesinwhich is a sliding pivot bolt'70 having 'a square shoulderflo Uponsaid bolt is a sleeve 70 having a shoulder 70 Upon the bolt 70 is athunib screw 69*. The'lowerend, of a bar 71 fits over the sleeve 70 onthe bolt 70. The other end of said bar extends upwardly a short distanceand with which end is pivotally connected zit 72, the lower end of ashort bar 73, Upon the upper end of the bar 73 is connected rigidly oneside Cportion'jof :a U shaped trunnion grasping yoke hr jaw 74,.extending inwardly beyond the line of the lower surface oi the bar 73and consistingof a plate bent in the arc ofa circle and extended abouttwo thirds the distance in the direction'of the line of thecircumferenceof the trunnion 56, a portion 74 of which U shaped portionextends laterally and inwardly and upon the "inner surface of whichjjawsare ratchet teeth. engaging with the ratchet teeth 68' upon the saidtrunnions. .Infthe outer curved surface of the plate 74 is a groove 74which receives theflange 67. The sides of the opening 76 in plate 75leading to the ratchet teeth are the proper distance apart {to'reg isterwith the opening 66 in plate 63 ior the entrance oi the trunnions 56,the connection .of the plate 74 being made with the-plate 63. when theseparate'parts are united with the bar 62. Whenthe trunnionsare 111-,troduced within the openings 66 and 76 thefra'tchet teeth on thetrunnions engagewith the ratchet teeth 75 in plate 74, the broilerresting upon the flanges-25 in the case. Upon the outer free end of oneof the, bars 62 supportingthe trunnion 56 is a handle 77.

In the side 21 of the case to which the-bar 59 is hinged and at a pointequi distant-from theline of the ends 22, 22 of the case isa verticalslot 78 which extendsfrom a point a short distance below-a line parallelwith the under surface of the bar 59 and down wardly to a point abovealine extending horizontally through the flanges 25. Upon the outersurface of the side 21 of the case below the lower end'of the slot isrigidly connected the lower end of aspring plate 79 the upper end ofwhich plate is .bent inwardly within the slot 78, then bent at an angletoitseli andextended upwardly and outwardly from the upper portion ofsaid slot forming a V shaped hook 'or 'spring catch80 the position'lofwhich is .just above one side of the lower frame or the broiler as seenin Fig. 3.

In the employment of the broiling apparatus the cover 31 is removed-irorn the flue opening 29 and the flange 30"connected with a pipeleading to an open fire place or chimney orother exitor draft openingfor smoke. Gas-is admitted to theburners 32 by opening the valves 48.These burners 32 arelarger than the ni pples'46 thus adapting theapparatus to the use of either natural" orz'artificial hydro carbon gaswhich is admitted through the conducting pipe 54. In the employment ofthe former gas the grate 27 upon each side of the longitudinal slots 39may lie covered with broken terra cotta or fire proof material whichwill absorb heat and radiate the same under low fire and the firetempered so that the roasting may be gradual without liability ofburning the gas permeating the material. During the roasting the draftupon the opening 29 acts to cause a down draft of the smoke and vaporand also. of the unconsumed gas which passes through the openings 39,into the chamber 28 and thence out of the chamber through the saidopening and preventing the smoke and odors from entering the room andalso preventing the deleterious action of gas on the meats. If preferredthe cover 44-may be removed from the open ing 42 in the bottom 23 of thecase and the case placed upon the stove or range, from which the coverhas been removed and the opening 42 caused to register with the 7opening in the range thus utilizing the natural draft of the stove orrange to carry off the smoke. The drippings from the meat in broilingwhich will escape in some degree before the meat is seared will fallupon the flanges 38, the apertures 39 being above the hori- Zontal planeof the burner so that the down draft will not be impeded by clogging ofthe apertures. The drippings which fall upon the flanges are conductedto the upper surface of the flanges 37 in the heat of the burner and arecarbonized the smoke passing through the apertures 39.

In order to raise the broiler 'from the supporting flanges 25 power isapplied to the handle 77 and the frame 58 is raised upon its hinges 61and at the-same time an initial start toward rotation of the broilerframes 55 is imparted by the spring hook 80 and the pivoted bars 71 and73 are extended, the jaws simultaneously maintaining a rigid grasp uponthe trunnions 56 of the broiler and causing rotary,movement to beimparted to said frame and upon the completion of the upward movement ofthe supporting lever arms 62 the bars 71 and 7 3"are in line with eachother the U shaped jaw 74 being in a reversed position with the opening76, turned past the opening 66 in the bearing 63 and in a downwarddirection,thus locking the trunnions and the broiler frames in themeantime being also in a reversed position for exposing other portionsof the mcatto the fire the position of the jaw 74 being such as toprevent the dislodgement of the trunnions from the raising and loweringframe and the U shaped journal bearings '63. When the broiler is loweredin position the openings 66 on the journal bearing and the openings 7 6to the jaws 74 register with each other and in which position thetrunnions on the broiler may be raised out of the said openings. Inlowering the frame 58 with the broiler the ratchet 75 upon plate 74 andthe ratchet teeth 68 on the trunnions 56 slip past each other and thebroiler frame moves downwardly tothe position for roasting as before.The lever arms 62 rest at all times upon the pivot bolt 70 and may beraised and lowered to adjust the height of the bar 71 to the heightnecessitated by the trunnions 56 by thumb screw 70 Instead of frame 58for raising and lowering the broiler I may employ the modifiedconstruction as seen in Fig. 11. The case 81 as seen in said'figure. issub-.

spring catch 84. This rod extends a short distance beyond the ends 83 ofthe case' and is fulcrumed or journaled in the brackets 86 which areconnected with the said ends 83 of the case the upper ends of thebracket being inclined a slight distance outwardly and beyond. the upperoutwardly inclined portion of the sides 82 of the case. The ends of therod 85 are bent at right angles to form lever arms and extended to aposition opposite the openings 87 in the ends of the case which openingsare the same as the openings 24 in Fig. 1'. Said ends of the rods arebent upwardly and extended rearwardly a short distance in the arc of acircle as at 88. Upon the upper surface of the said ends'of the rodsadjacent to the bent portion 88 are ratchet teeth 89. The trunnions 90of the broiler are held between spring clips 91 consisting of a plateextending in an arc of a circle on 'Upon the trunnions are ratchet teeth92 as in Fig. 1 which engage with the ratchet teeth upon the ends of thelever arms on rods 85. Upon the rod is a short arm 93 upon which is adetachable handle 94. Connected pivotally at one end with the portion ofthe clips 91 on the ends of lever arms on rod 85 are rods 95 the otherends of which rods are extended forwardly and connected pivotally withthe ends 83 of the case near the parallel side 82 of the case. Thebroiler is raised repeatedly in this modification by the power appliedto the handle or arm 94 inwhich'movement the clip 91 supporting thetrunnions 90 move in opposite directions, the teeth upon the rodobtaining a grasp upon the ratchet teeth upon the trunnions 90 in eachforward movement of the clips and imparting rotation to the trunnions90, the bendingof the,upper portions of the sides of the box outwardlyaffords space for the movement of the frame of-the broiler. In therepeated movements upwardly and downwardly of the broiler frame theportion'of the frame toward the side 82 comes forcibly into contact withthe spring plate 84 and upper surface of the hooks obtaining in eachimpact an initial movement upwardly to assist the rotation of thetrunnions by the ratchet teeth.

The ratchet teeth upon the jaw 74 as in Fig. 1 may be dispensed with ifdesired and the surface left smooth as seen in Figs. 10 and 10 In thisconstruction the jaw 96 will obtain a fractional grasp upon thetrunnions which as shown in Fig. 9 in section will be made withcorresponding frictional surfaces. I

It is obvious that instead of the broiler frames as shown an ordinaryspit may be employed of which the trunnions will form an integral partas seen in Fig. .12

' in which 97' is the spit 98 the trunnions rotation being imparted tothespit as the spit is raised in position in corresponding manner withthe rotation of the broiler frames. The spring plate 79 may be dispensedwith and such other modifications employed as are within the scope ofthe invention.
